I havea poodle, bechon mix and he ate chicken bones.

Has been having diarea with blood.

Its been about 4 days.

What should I do?

You need to get off the computer and take your dog to the vet right now or he may very well die.

Buddy, 4 days? Splinters from chicken bones can perforate the stomach and/or bowels. If you haven't listened to bushg, pick up the stool, put it in a plastic bag, and get both that sample and your dog to the vet ASAP. She is right. Your dog can die from this.

You should take it to the vet before it can get very sick and even die the vets will give your dog a special treatment good luck bye
